Virtual tires in the early vehicle development phase
@inproceedings{Niedermeier2013VirtualTI, title={Virtual tires in the early vehicle development phase}, author={Florian Niedermeier and Ulrico Peckelsen and Frank Gauterin}, year={2013} }
Pacejka’s Magic Formula (MF), a semiempirical tire model, is nowadays the worldwide standard for vehicle dynamic simulations [1. [] Key Method They can be set either according to a simple measurement on a tire test rig, or to the specification of the user. These tire CVs are then used to generate a MFparameter file. A genetic algorithm achieves the best fitting results. Possible applications are the modification of specific tire characteristics, a global sensitivity analysis (between tyre CVs and the…

It is pointed out that if the number of points is not large enough in terms of the dimension then nearly the lowest possible L 2 -discrepancy is attained by a pathological point set, and hence the L 1 -Discrepancy may not be very relevant for relatively small sets.
